IMPROVEMENT IN FEED-WATER. HEATERS.

Specification forming part ot' Letters Patent No. 432,533, dated April 26, 1864.

To all whom it may concern Be it known that I, JOHN RANDOLPH SEEs, ot the city ot' New York, in the State ot'New York, have invented a certain new and useful Improvement for Heating the Feed-Water ot' Steam-Boilers; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the aecompanying drawings, and to the marks and letters thereon.

My improvement, though more especially designed for marine boilers, may be used in land, or stationary, or portable boilers. The drawings, forming part of this speeieation, show this improvement attached to a horizontal tubular boiler, Figure l of the drawings beinga side View ot' the smoke-box and a small portion of the boiler, the heater being indicated by red lines, and Fig. 2 being a front View of the smokebox and the heater contained therein. In both of these figures, where like parts are shown, like marks and letters are used to indicate thev parts. Within the smoke-box c is placed a hollow diaphragm, b, made otl corrugated plates, which are so secured to each other as to render the diaphragm wattr-tight. The interior of the diaphragm at the bottom, by a pipe, c, is in communication with the valve-chamber d of the feedpump, and at the top in communication by another pipe, e, with the Water-space ot' the boiler.` From the upper end of the valvechamber d a circulating-pipe, f, passes to the water-space of the boiler. The pipe from the feed-pump is attached to the lower end of the valve-chamber, and hence when the pump is in action the track of the water is through the valVe-chamberinto the pipe c and into the interior ot' the diaphragm, and from the diaphiagm through the pipe e into the water- Then the pump is not space ot' the boiler.

in action, there will be a cireuation ot' water through the diaphragm by the falling down of the Valve on its lower seat, and the communication being through the pipef, valvechamber d, pipe c, the interior ot' the diaphragm, andv pipe e. On the one side the diaph ra gm is supported by thepipes and the other side by rods, the bottom supports being trunnions, which are screwed or ilanged in, as occasion may require. The diaphragm is inclined, as shown by Fig. l, and the way I determine the set is to take the united area ot' the tlues and allowjust that area between the top ot' the diaphragm and the flue-sheet ofthe boiler, and then, both areas being the same, the draft is not al'eeted, and there is no occa` sionever after to alter the diaphragm. At any convenient point in the bottom ot' the dia phragm-heater a hole may be made, into which can be screwed a gage cock, so that at any moment the cock may be opened and any mud or sediment in the heater may be blown out. By making the diaphragm-heater of corrugated plates more heatingsurtace is obtained than when made of plain plates, and the corrugations stay the sheets or plates, so that bolts or stay-rods will not be required. This heater may easily be so hung or sustained in the smoke-box as to readily allow access to the tubes or fines for cleaning or breeching.

Vhat I claim as my invention, and desire to secure by Letters Patent, is-

The corrugated diaphragm feedwater heater, attached in the manner and for the purposes herein set forth.

This specication signed this 30th day otl September, 1863.
